Wasatch Fault
The Wasatch Fault is an active fault located primarily on the western edge of the Wasatch Mountains in the U.S. states of Utah and Idaho. The fault is about long, stretching from southern Idaho, through northern Utah, before terminating in central Utah near the town of Fayette. The fault is made up of ten segments, five of which are considered active. On average the segments are approximately long, each of which can independently produce earthquakes as powerful as local magnitude 7.5. The five active segments from north to south are called the Brigham City Fault Segment, the Weber Fault Segment, the Salt Lake City Fault Segment, the Provo Fault Segment and the Nephi Fault Segment. The Wasatch Fault is a normal (vertical motion) fault which forms the eastern boundary of the Basin and Range geologic province which comprises the geographic Great Basin. The Wasatch Mountains have been uplifted and tilted to the east by movement of the fault. The average vertical displacement ...

Great Basin
The Great Basin is the largest area of contiguous endorheic watersheds, those with no outlets, in North America. It spans nearly all of Nevada, much of Utah, and portions of California, Idaho, Oregon, Wyoming, and Baja California. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin in Death Valley to the highest point of the contiguous United States, less than away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts. Definition The term "Great Basin" is applied to hydrographic, biological, floristic, physiographic, topographic, and ethnographic geographic areas. The name was originally coined by John C. Frémont, who, based on information gleaned from Joseph R. Walker as well as his own travels, recognized the hydrographic nature of the landform as "having no connection to the ocean". The hydrographic definition is the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Idaho
The Geology of Idaho is complex, with outcroppings of differing ages of volcanics, undifferentiated metamorphics and sedimentary structures. Idaho Geologic Survey Since 1919, the Idaho Geological Survey (formerly Bureau of Mines and Geology) has studied and reported on the general and environmental geology of the state. The Survey also studies and reports on the water (both surface and ground), mineral data, and energy assets of the state. Geologists and hydrologists on staff at the Survey research, make reports based on their research, and produce maps for the state. The University of Idaho administers the Survey as a special program with offices in Moscow and in Boise. Regions Panhandle The region of the Idaho Panhandle reaches from the Canada–US border south to Interstate Highway 90. The area consists generally of Precambrian sedimentary formations, some of which have metamorphosed into slates. The area includes the Selkirk Mountains, the Purcell trench and the Cabi ...

Geology Of Utah
The geology of Utah includes rocks formed at the edge of the proto-North American continent during the Precambrian. A shallow marine sedimentary environment covered the region for much of the Paleozoic and Mesozoic, followed by dryland conditions, volcanism and the formation of the basin and range terrain in the Cenozoic. Utah is a state in the western United States. Geologic History, Stratigraphy & Tectonics The eastern Uinta Mountains near the Colorado line and the Raft River-Dover Creek Mountains contain the oldest rocks in Utah from more than two billion years ago. Rubidium-strontium dating of the Red Creek Quartzite in 1965 indicated an age of 2.3 billion years. Other geologists found 2.4 billion year old schist and gneiss in the Albion Range Green Creek Complex. Prior to the 1960s, geologists inferred the Vishnu and Farmington Canyon gneiss and schist as Archean in age, but subsequent research indicated an formation between 1.6 and 1.5 billion years ago in the Proterozoic ...

Seismic Retrofitting
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.), many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried out. State-of-the-art technical guidelines for seismic assessment, retrofit and rehabilitation have been published around the world – such as the ASCE-SEI 41 ...

Magna, Utah
Magna ( ) is a metro township in Salt Lake County, Utah, United States. The current population of the township stands at 29,251 according to the 2020 census, a 10.4% increase over 26,505 in 2010. History Settlement Settlement of the area began in 1851 shortly after pioneers reached the Salt Lake Valley. Early farmers settled in 1868 at the base of the northern Oquirrh Mountains and called their community Pleasant Green. By 1900, there were about 20 families in the area. One of the first Pleasant Green farmers was Abraham Coon, who established a livestock ranch and settlement called Coonville in a canyon mouth at about 5400 South now known as Coon Canyon. Coon Creek flows out of Coon Canyon and is one of the major Oquirrh Mountain drainages. Coon Creek flows north and west through Magna to the Great Salt Lake. The Pleasant Green Cemetery located in the Oquirrh foothills, at about 3500 South, was established in 1883. In 1890, in response to a law requiring all children to rece ...

2020 Salt Lake City Earthquake
At 7:09 AM MDT on March 18, 2020, a 5.7 magnitude earthquake hit Salt Lake City, Utah, United States, with an epicenter north-northeast of Magna, Utah, beneath the site of the planned Utah Inland Port. It was the first major earthquake to occur within the Salt Lake Valley since the city was founded, the state's strongest earthquake since the 1992 St. George earthquake, and the first earthquake of comparable magnitude to occur near Salt Lake City since 1962, when a magnitude 5.0 earthquake struck a similar location in Magna. Geology Salt Lake City lies at the eastern boundary of the Basin and Range Province. The major active fault zone is the normal Wasatch Fault that throws down to the west. The footwall (upthrown part) is formed by the Wasatch Range with part of the Great Basin lying in the hanging-wall (downthrown part), at one time filled by Lake Bonneville, with the Great Salt Lake forming the largest remnant. The fault zone is broken up into six segments that ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subsidence
Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement. Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater; gradual compaction of sediments; withdrawal of fluid lava from beneath a solidified crust of rock; mining; pumping of subsurface fluids, such as groundwater or petroleum; or warping of the Earth's crust by tectonic forces. Subsidence resulting from tectonic deformation of the crust is known as tectonic subsidence and can create accommodation for sediments to accumulate and eventually lithify into sedimentary rock. Ground subsidence is of global concern to geologists, geotechnical engineers, surveyors, engineers, urban planners, landowners, and the public in general.National Research Council, 1991.

Lake Bonneville
Lake Bonneville was the largest Late Pleistocene paleolake in the Great Basin of western North America. It was a pluvial lake that formed in response to an increase in precipitation and a decrease in evaporation as a result of cooler temperatures. The lake covered much of what is now western Utah and at its highest level extended into present-day Idaho and Nevada. Many other hydrographically closed basins in the Great Basin contained expanded lakes during the Late Pleistocene, including Lake Lahontan in northwestern Nevada. Geologic description Shorelines of Lake Bonneville are visible above Salt Lake City along the western front of the Wasatch Range, Wasatch Mountains and on other mountains throughout the Bonneville basin.Gilbert, G.K., 1890. Lake Bonneville. U.S. Geological Survey Monograph 1. 438 pp. These shorelines appear as shelves or benches that protrude from the mountainside above the valley floor, are visible on the ground from long distances and on satellite images, a ...
